Causes of pollution in Delhi
Growing population of the city. The pressure and haphazard growth of the population is deteriorating the environment.
There has been highly haphazard and unplanned development of industries and factories. Studies have revealed that only about 20% of the industrial units are set up in the approved industrial areas whereas the rest of them are in residential and commercial areas.
There has been a huge rise in the vehicular population, in spite of the metro railways, aggravating traffic congestion and increasing air and noise pollution. It has also been reported that the number of vehicles plying on the roads of Delhi is more than that of the three metropolitan cities of Mumbai, Kolkata and Chennai taken together.
There has also been an ever-increasing number of diesel vehicles plying on the roads, which are largely responsible for the air pollution.
It has been reported by the National Environmental Engineering Research Institute (NEERI) that everyday almost 8,000 m tonnes of solid waste is being generated in Delhi. Plus we also have the industrial hazardous and non-hazardous waste. On an average, everyday, the MCDs and the NDMC manage to clear about 5,000-5,500 m tonnes of garbage. This results in the accumulation of more and more garbage in the city.
There has been no proper technology or methods to treat solid, liquid, waste water, industrial and hospital wastes in the city.
There has been too much dependence on fossil fuels like coal-fired power plants, improper use of energy in buildings and the excessive use of biomass for cooking and heating, etc
Particulate matter for measuring pollution
One way of measuring pollution is by the measure of particulate matter. Particulate matter is basically a mixture of extremely small particles and liquid droplets like acids, chemicals, gas, water, metals, soil dust particles, etc., the measurement of which gives an idea of the pollution of a city. It is also known as particle pollution or PM.
Pollution in Delhi: Facts and figures
According to the Ambient Air Pollution (AAP) report for the year 2014, Delhi had PM 2.5 pollution levels, which is the highest in the world, followed by Beijing. This result was based on the monitoring of PM measurement of outdoor air pollution from almost 1,600 cities in 91 countries.
The highest concentration of PM 2.5 form of air pollution is supposed to be a very serious matter and can lead to respiratory diseases and other health problems like lung cancer.
According to the WHO, air pollution is the fifth largest killer in India.
Carbon monoxide (CO), a dangerous gas emission, is around 6,000 microgram per cubic metre in Delhi, which is much above the the safe level of 2,000 microgram per cubic metre.
The level of nitrogen dioxide (NO2) has also been increasing.
According to the Ministry of Earth Sciences, Delhi’s air quality index (AQI) is 121, which is described as “poor.” The AQI is an index for reporting daily air quality, about how clean or polluted the air is.
It has been estimated that Delhi is going to become world’s most populated city around 2028 as per the United Nation’s Statement. National Capital region of India is considerably attracting more people every year towards it. As per the estimation of 2016, Delhi was populated with 18.6 million people and the count just reached 28,513,682 by 2018.
People in rural areas are approaching towards urban settlement in order to improve their economical situations and lifestyle. The action of approaching urban settlement has been considered as one of the important reason for the population explosion in Delhi. Explosion of large level pollution has been founded as one of the main result of population explosion in Delhi.
other than population, growth of industries and higher production of wastes are the other reasons for the increase in pollutant level in Delhi.
